I appreciate your efforts to teach us! Awesome video. I especially like that you focus not only on design examples but on fundamental things and patterns also. These are much more helpful to become confident on the interview.

[NavneetVermalivefree]

can you make a video on how on the Ad bidding system design. I think there will a lot things going in those systems. In this video you covered some part, but it would really help if you can go in more details.

[Wei-upjn]

[castkro]

I feeling like, to be a system designer you have to know everything, like you have to be a Full Stack Developer, DevOps and everything

Nice video, but I think there is a mistake. 7:49 WAL is file which is stored on disk and is used for recover from failures. In your example it should be in RDBMS/Disk table.

[dataguy]

Naren, what is the diff between Distributed cache and real time DB. Is it that, in real time DB, you have a query language and a cache you dont have SQL but need to write your own APIs

[saidattathallam]

Aerospike uses LSM tree and btrees to index the SSTables. Their architecture did not mention about AVL trees.

[大盗江南]

As usual, super great video. Thank you so much seriously, bro!

[SumanAmara]

Hi nice sir can take a video about memsql it is going to be game changer in IT ...

[dataguy]

Naren, what is the reason for using AVL for in memeory. Why not just a tree structure? The why would be helpful

[vishalgupta-twyt]

1) How does WAL handle concurrent updates. Could there be a scenario where 2 conflicting updates are applied in different order in inmemory database and the backup database
2) what happens if the update in the in memory database succeeds but the write to the WAL fails ?
